As far as I know, the chemicals put in a boat's head is for odor purposes,
other than its lubricant value for the pump. There are no enzymes put into the
chemicals that eat away the bacteria. I don't believe it would do any good for
a household's septic system unless you are using an ejector pump that sends the
waste to an interior or above ground holding tank.
